DTC 92-1X ("X" CAN BE 0 THRU 9 OR A THRU F): OPEN IN PASSENGER'S AIRBAG CUTOFF
INDICATOR

1. Clear the DTC memory (see CLEAR THE DTC MEMORY WITH THE HDS ).

2. Turn the ignition switch ON (II), and check that the SRS indicator comes on for about 6 seconds and

then goes off.

Does the SRS indicator stay on, and is DTC 92-1x indicated?

YES - Go to step 3.

NO - Intermittent failure, the system is OK at this time. Go to TROUBLESHOOTING
INTERMITTENT FAILURES . If another DTC is indicated, troubleshoot the DTC.

NOTE:

Before doing this troubleshooting procedure, review SRS Precautions and
Procedures (see PRECAUTIONS AND PROCEDURES ) and General
Troubleshooting Information (see GENERAL TROUBLESHOOTING
INFORMATION ).

3. Disconnect the passenger's airbag cutoff indicator 6P connector (see PASSENGER'S AIRBAG

CUTOFF INDICATOR ILLUMINATION BULB TEST ).

4. Turn the ignition switch OFF. Disconnect the negative cable from the battery, then wait for 3 minutes.

5. Disconnect SRS unit connector A (28P) from the SRS unit (see step 7 ).

6. Reconnect the negative cable to the battery.

7. Turn the ignition switch ON (II).

8. Measure the voltage between the No. 12 terminal of SRS unit connector A (28P) and body ground.

There should be 0.5 V or less.

Is the voltage as specified?

YES - Faulty SRS unit or passenger's airbag cutoff indicator; replace the passenger's airbag cutoff
indicator. If the problem is still present, replace the SRS unit (see SRS UNIT REPLACEMENT ).

NO - Short to power in dashboard wire harness A; replace dashboard wire harness A.

DTC 92-2X ("X" CAN BE 0 THRU 9 OR A THRU F): OPEN OR SHORT TO GROUND IN
PASSENGER'S AIRBAG CUTOFF INDICATOR

1. Clear the DTC memory (see CLEAR THE DTC MEMORY WITH THE HDS ).

2. Turn the ignition switch ON (II), and check that the SRS indicator comes on for about 6 seconds and

then goes off.

Does the SRS indicator stay on, and is DTC 92-21 indicated?

YES - Go to step 3.
